Java and distributed object models are important for building modern, scalable, interoperable applications. This paper is focused on the performance analysis, comparison and optimization of the three most important distributed object models for Java: RMI (Remote Method Invocation), RMI-IIOP beta (Remote Method Invocation over Internet Inter-ORB Protocol), and IDL (Interface Definition Language)...

This paper is focused on the performance analysis, comparison and optimization of the most important distributed object models for Java: RMI (Remote Method Invocation) and RMI-IIOP (Remote Method Invocation over Internet Inter-ORB Protocol). The paper presents the following contributions to the research on distributed object performance. First, a detailed performance analysis of both models is ...

Java Remote Method Invocation (RMI) is a built-in and easy-to-use framework for the distribution of remote Java objects. Its simplicity and seamless inter-virtual machine communication has made it a valuable tool for distributed services. It nevertheless exhibits certain constraints that practically limit RMI applications to the classical client/server distribution model, and make highly distri...

In current Java implementations, Remote Method Invocation (RMI) is too slow, especially for high performance computing. RMI is designed for wide-area and high-latency networks, it is based on a slow object serialization, and it does not support high-performance communication networks. The paper demonstrates that a much faster drop-in RMI and an e cient serialization can be designed and implemen...

Remote Method Invocation (RMI), a mechanism to access remote objects in Java-based distributed applications, uses network communication for each method invocation. Consequently, using RMI in a wide-area environment can cause poor application performance. One solution to improve performance is to cache the objects such that network communication is not necessary for each method invocation. In th...

Abstract. The Relativistic Motion Integrator (RMI) consists in integrating numerically the EXACT relativistic equations of motion, for a given metric (corresponding to a gravitational field at first post-Newtonian order or higher), instead of Newtonian equations plus relativistic corrections. The aim of the present paper is to validate the method, and to illustrate how RMI can be used for space...

Java Remote Method Invocation (RMI), as a distributed object technology, has poor existing support for operation in wireless mobile computing environments. The use of RMI in a mobile environment poses a number of problems related to hardware mobility and the characteristics of wireless networks. This paper describes an implementation of an architecture supporting RMI client and server applicati...
